That sounds about right, they are pretty soft and the slide stakes harder than the receiver. The difference between the slide and frame may be why it does not gall. Slide-1050 hot rolled but not annealed. Has to be somewhat harder than the frame. 1050 would easily case harden, but all the thin areas would get brittle. You would not even have to carborize. I used to HT 1040 by throwing it in salt slush.
